Hi,
I want to my ESP32 when it is sleep (in mode light_sleep) and I will do a long pressed button ( maybe 5 seconds ) and want esp32 can transfer to deep_sleep().
Is it possible to do it ? Thanks a lot for helping me.

I have a .bin . The content suppose is [0x00 0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0A,.....].
How can I use fwrite into this .bin file to make the content of this file is [0x00 0x01 0x02 0x03 0x0F 0x0F 0x0F 0x0F 0x08 0x09 0x0A,.....].
Tks a lot.

Tks for your reply.

Hi everyone, I have 2 ESP32 , ESP32 1 is master and ESP32 2 is slave. I want to let the ESP32 master use .bin file in SPIFFS to update firmware for the ESP32 slave (may be via serial). If anyone has sample code for this, please let me know. Thank you very much.
